In July 2012, it was reported that Bob Feldstein, the corporate vice president of business development at AMD, left the company to go to work at NVIDIA. Now AMD has filed a lawsuit against Feldstein and three other ex-AMD workers claiming that they stole over 100,000 secret documents from the company.

AMD says that some of the files that were taken include “two licensing agreements with significant customers, and a document outlining proposed strategies to AMD‘s strategic licensing.” AMD says that if these secrets were revealed to a competitor, such as NVIDIA, it would offer them “an unfair advantage.”

AMD is seeking a temporary restraining order against the four people listed in the lawsuit along with a court order to preserve any copies of the electronic documents they may have taken. So far, there’s been no comment from the four ex-AMD employees nor has there been any comment from NVIDIA.

Before leaving AMD, Feldstein was credited for securing agreements with Microsoft to have its Radeon graphics chips inside the Xbox 360 game console, along with the Wii and Wii U consoles from Nintendo. It’s rumored that the next game consoles from Sony and Microsoft will also have AMD made processors and graphics chips inside.
